Pilots loyal to outstanding O.S. performance but eager to fly electric now have the ideal option — powering electric airplanes using new O.S. brushless motors! Designed by O.S. engineers to be the "gold standard" in electric power, these motors offer the same legendary quality and reliability that have O.S. glow engines famous worldwide for 75 years. Only O.S. brushless motors offer a ventilation system that increases efficiency and allows the motors to generate additional power. Key to this system is a unique centrifugal fan design. The fan draws air through specially angled ventilation holes, across the windings and over the magnets for greatly improved cooling.

    Looking to use this OMA 5025-375 in the new Prometheus 50e on 8s and a 15x8 or 15x10 propeller. I have not run it yet, but I am confident that it will perform to expectations having read a lot about it in the forums.
